Doctors have given Mets righty Matt Harvey reason for optimism in assessing his recovery prognosis after surgery to address thoracic outlet syndrome, his agent Scott Boras said today. MLB.com’s Anthony DiComo reported the latest on the star hurler.

“You kind of rely on the doctors here, and the doctor was extremely positive about the results of what he found when he did the operation, and the relief that he gave Matt,” said Boras. The surgeons were clear that they viewed the procedure as a success, the agent emphasized. “The doctor was very clear,” he said. “The doctor’s certainty is that he was able to give a nerve space so it could function normally.”

In his comments today, Boras also revealed some details about just what Harvey was dealing with in his abysmal 2016 season. “It was really just a nervecompression,” Boras explained. “[Harvey] didn’t have sensation [in his fingers]. And so clearly, the procedure allowed that relief where the nerve is now free and he should have full feeling in his hand.”

That Harvey was pitching with that kind of challenge seemingly helps explain his results. Though his velocity was largely in line with his career numbers, the 27-year-old not only scuffle to a 4.86 ERA in his 92 2/3 innings, but gave up 111 hits in that span and managed only 7.4 K/9 on the year.

The expectation in Harvey’s camp seems to be that he’ll be able to ramp up for a normal Spring Training. Harvey plans to build up his conditioning and finish off his rehab over the winter. Harvey has already resumed throwing.

It goes without saying, but the news seems to be highly promising for a Mets organization that has had a startling run of health issues in its rotation after pushing the unit hard in 2015. The club ought to have a chance to make at least a preliminary assessment of Harvey, Jacob deGrom, Steven Matz, and Zack Wheeler before deciding how hard to push for added pitching depth over the winter.

Tonight represented the end of the illustrious career of Red Sox slugger David Ortiz, as Boston was knocked out by the Indians in a sweep. The 40-year-old’s twentieth season in the majors was one of his best, as he led the league in slugging percentage and OPS (with a .315/.401/.620 batting line) while knocking 38 long balls in 626 plate appearances. Despite the team’s disappointing end to the year, the Fenway Faithful stayed on hand long after the game for one final in-uniform curtain call. MLBTR offers its congratulations to a player who was one of the greatest designated hitters ever to suit up. All told, he racked up over 10,000 MLB plate appearances with a monster .286/.380/.552 slash line and 541 home runs — 17th most in major league history.

As the Hall of Fame debate begins in earnest on Ortiz, here’s more from around the game:

MLB commissioner Rob Manfred expressed optimism that there will be a positive resolution in “relatively short order” on the Athletics’ quest for a new park, as John Shea of the San Francisco Chronicle (in a tweet) and Joe Stiglich of SportsNet California (Twitterlinks) were among those to report. Nothing seems to be imminent — Manfred suggested that something will come together within the next year — but it nevertheless seems that there’s some forward progress. He suggested that there are still several potential sites being explored in Oakland, with mayor Libby Schaaf having “made it clear to [Manfred] that baseball is her first priority.”

Bob Dutton of the Tacoma News Tribune takes a long look at the Mariners’ many roster decisions this winter. Among other things, he notes that Seattle is open to bringing back Drew Storen, though the sense is that the reliever will look for a late-inning opportunity elsewhere. He also breaks down the decisions on many arbitration-eligible relievers; you can find their projected arb salaries right here. In the field, Dae-ho Lee could be retained as a righty option at first, but that’s no certainty. And one of the biggest questions is at short; Dutton notes that the club intends to look into a veteran option after a tough year for Ketel Marte.

The Orioles may face a call on young first baseman Trey Mancini, Roch Kubatko of MASNsports.com explains. He had a solid season in the upper minors, but swatted three long balls in just five games of major league action late in the year. Some might suggest that the O’s shift Chris Davis to right field, but Kubatko suggests that’s not a likely outcome. And while Mancini could get a look there, the club hasn’t seemed optimistic about such a move. Instead, perhaps, he’ll more likely push for a spot in the DH mix — but could end up back at Triple-A, at least to start the year.

Matt Harvey remains a wild card for the Mets after undergoing surgery to help alleviate thoracic outlet syndrome, but there’s a bit of good news on that front. Harvey is already able to throw, as he posted to his personal Instagram account. His specific timeline remains unclear, but that would seem to suggest that he’ll be ready for a full spring.

Harvey was placed on the disabled list earlier this week, and it was reported soon after that he was to be evaluated for thoracic outlet syndrome — a compression of nerves and blood vessels in the shoulder area that is often alleviated by the removal of a rib in the patient. Twins right-hander Phil Hughes underwent the same procedure earlier this week, and other recent examples of players to undergo the procedure include Chris Carpenter, Jaime Garcia and Chris Young.

The loss of Harvey is magnified by the fact that two of the Mets’ excellent young starters, Steven Matz and Noah Syndergaard, are pitching through bone spurs in their elbows. Matz’s spur is said to be the larger and more severe of the two, and surgery has been mentioned as an option for him as well, though he’s hoping to delay the procedure until the offseason, as going under the knife would essentially end his 2016 campaign as well. Right-hander Zack Wheeler, too, has suffered some setbacks in his recovery from Tommy John surgery and doesn’t currently have a projected return date.

Mets righty Matt Harvey has been found to have symptoms consistent with thoracic outlet syndrome, GM Sandy Alderson told reporters including MLB.com’s Anthony DiComo (Twitter link). Harvey is still weighing whether to have season-ending surgery now or instead to undergo a therapy for the time being. ESPN New York’s Adam Rubin writes that the alternative to surgery would be a nerve-block injection, though that would merely be a temporary fix to the problem at hand. Surgery to alleviate his symptoms are inevitable, but it’s possible that he could delay the procedure until the offseason if he elects the injection route.

Harvey’s dilemma marks a continuation of injury problems that have impacted the Mets’ much-ballyhooed young rotation. Right-hander Noah Syndergaard is pitching through a minor bone spur in his right elbow, while lefty Steven Matz is currently pitching through a bone spur in his own elbow that is said to be larger than that of Syndergaard. And, of course, the Mets have been without the highly talented Zack Wheeler since 2014, as the now-26-year-old righty underwent Tommy John surgery just prior to Opening Day 2015. Notably, DiComo tweets that Wheeler isn’t an option to replace Harvey anytime in the near future, as the club has stopped providing a timetable for his return.

The 2016 season has been a struggle for Harvey, as he’s pitched to a 4.86 ERA with diminished strikeout (7.4 K/9), walk (2.4 BB/9) and ground-ball (40.8 percent) rates while also seeing a 1.5 mph dip in his fastball velocity. Those hardships come on the heels of a 2015 campaign in which his innings total was the source of a prolonged controversy. There was talk of shutting Harvey down for the year, as he had undergone his own Tommy John surgery in 2014, but he ultimately tossed a combined 216 innings between the regular season and the playoffs — the highest total ever for a pitcher in his first full season back from Tommy John. Of course, it’s not clear that last season’s workload had any direct impact on his new injury.

From a replacement standpoint, the Mets have a number of options, as can be seen on their depth chart. Logan Verrett will start this weekend in Harvey’s place and could be a rotation option alongside Syndergaard, Matz, Jacob deGrom and Bartolo Colon. Alternatively, Sean Gilmartin could make some starts for the club after enjoying a successful 2015 run as a member of the bullpen following his selection in the Rule 5 Draft (he’s been starting at Triple-A this year). Rafael Montero could again be an option, though he’s struggled tremendously in the minors this season. Right-handers Robert Gsellman and Gabriel Ynoa are in the Triple-A rotation and already on the 40-man roster. And, the Mets have also already brought Seth Lugo up to the Majors once this season and could turn to him for spot starts or long relief work if needed.

5:07pm: Harvey is seeing Dr. Thompson to check out the team’s “suspicion” that Harvey could be dealing with thoracic outlet syndrome, Newsday’s David Lennon tweets. The syndrome involves a compression of nerves and/or blood vessels in the shoulder area, and can be quite painful.

4:35pm: The Mets have placed righty Matt Harvey on the 15-day DL, per a club announcement. The teams says that Harvey is dealing with right shoulder discomfort.

This news raises yet more serious concerns about a pitcher who already hasn’t looked himself this year. Expected to lead a rotation full of outstanding arms, Harvey has instead been the black sheep of the group, pitching to a 4.86 ERA with 7.4 K/9 and 2.4 BB/9 over 92 2/3 innings. There have been some ups and downs mixed in, but the aggregate falls shy of the ace-level results that Harvey has traditionally posted.

It’s not immediately clear whether this is a long-simmering issue or a newly-arising problem, but a glance at Harvey’s Brooks Baseball page shows one apparent change in recent weeks: a sudden and drastic shift in his horizontal arm slot. He’ll visit shoulder specialist Dr. Robert Thompson, who — as Marc Carig of Newsday notes on Twitter — is an expert in vascular issues such as thoracic outlet syndrome.

Harvey had returned from Tommy John surgery last year in dramatic fashion, logging 189 1/3 innings of 2.71 ERA ball with 8.9 K/9 and 1.8 BB/9. That was a largely unprecedented jump in innings for a pitcher who was working with a new UCL, and Harvey went on to throw another 26 2/3 in the post-season — which also shortened his winter rest period. While we haven’t heard of any elbow-related concerns, it’s hard not to wonder whether there could be any connection between that series of events and Harvey’s current malady.

New York has called up righty Seth Lugo to take Harvey’s place on the active roster, but he’s not an option to step into the rotation. For the time being, the club will likely go to swingman Logan Verrett, as they have on several prior occasions this year.

In the event that Harvey requires a lengthier absence, things could begin to get tricky. Steven Matz is pitching through a painful bone spur at the moment, so he’s a bit of a question mark, too. And the obvious replacement – Tommy John rehabber Zack Wheeler — is still not throwing bullpen sessions, per another Carig tweet. That’s still an enviable pitching situation, but a piece or two of bad luck could raise some real depth concerns with the cub’s key area of strength.

That’s not to say that there aren’t other pieces on hand. Former top prospect Rafael Montero is still pitching at Triple-A, but the results haven’t been pretty. Also working in Las Vegas are hurlers such as Gabriel Ynoa and Sean Gilmartin. Ynoa may be at the top of the team’s list among its farmhands, Mike Puma of the New York Post suggests on Twitter.

The Mets think they found a flaw in the delivery of struggling right-hander Matt Harvey, whose command is suffering because his arm is pausing/stopping, tweets FOX Sports’ Ken Rosenthal. Mets assistant general manager John Ricco expressed confidence Friday that Harvey’s on the right track mechanically. In his latest start, a loss to the Nationals on Tuesday, Harvey struck out only one batter while allowing eight hits (including three home runs), five earned runs and two walks across five innings. The 27-year-old was one of baseball’s premier starters from 2012-15 (2.53 ERA, 9.46 K.9, 1.98 BB/9 over 427 innings), but the 2016 version has gone the opposite direction. Harvey’s 6.08 ERA through 53 1/3 frames ranks fourth worst among the league’s qualified starters, while his strikeouts have notably declined (7.43 K/9) and his walks have increased (2.87 BB/9).

More from the Big Apple:

Michael Pineda, another righty amid a surprisingly subpar season, might not continue to have a spot in the Yankees’ rotation if his troubles continue. Pineda’s ERA ballooned to 6.92 Saturday after he gave up nine hits and six earned runs in a loss to the Rays, and pitching coach Larry Rothschild didn’t close the door on demoting him, per Brendan Kuty of NJ Advance Media. “We’d like to get him through this but our eyes are open with what goes on,” he said. “To win games is the most important thing for the team. So, in jeopardy, I don’t know. But we realize what’s going on.” The decision will ultimately rest with general manager Brian Cashman, whom manager Joe Girardi and Rothschild speak with on a daily basis.

Even if the Yankees do wish to use Pineda’s remaining option and send him to the minors, they’re not exactly overflowing with candidates to replace him, as George A. King III of the New York Post points out. The Bombers already had to demote the similarly disappointing Luis Severino, for whom they also had high hopes entering the season. For his part, Pineda doesn’t think his issues are related to health. “I feel strong. I feel good,” he said Saturday. Pineda’s velocity would seem to agree with that, and his K/9 currently sits at a career-best 9.96.

It was previously unclear how much time Mets first baseman Lucas Duda would miss after landing on the disabled list Monday with a stress fracture in his back. Mets general manager Sandy Alderson clarified Saturday, telling reporters – including ESPN’s Adam Rubin (video link) – that Duda should be out in the four- to six-week range. Thanks to Duda’s injury, the Mets acquired fellow lefty-swinging veteran James Loney from San Diego on Saturday to help fill the void at first.

Ryan Howard’s spot on the Phillies’ roster has been a consistent source of speculation for the past three to four seasons, but despite the fact that he’s having a career-worst year in the final season of his contract, GM Matt Klentak implied in an appearance on MLB Network Radio on SiriusXM (Twitter link) that Howard isn’t in danger of losing that spot. “He’s a threat to change the game with a home run every time he steps in the box,” said Klentak to hosts Jody McDonald and Cliff Floyd. “As long as that’s the case, he’ll be in there.” Howard is batting just .160/.226/.359 in 146 plate appearances, though he does have eight homers on the year.

A couple more from the NL East…

Mets assistant GM John Ricco was also a guest on MLB Network Radio recently (audio link), where he discussed Matt Harvey’s status in the rotation. “We have a team that’s built to go to the World Series, and we have to think about what’s best for the team,” said Ricco. “But right now, we believe the best thing for the team is getting Matt back on track, and the best way to do that is to keep him in the big leagues working with [pitching coach] Dan Warthen. We saw some positive signs the other night, in terms of the metrics we look at.” Asked specifically which metrics that statement referenced, Ricco explained that in addition to the traditional eye test from the coaching staff, technology provides quantifiable data on Harvey’s arm angle, arm extension, release point and other mechanically inclined metrics, which give the Mets confidence that he’s making some strides.

Newsday’s Marc Carig writes that with the struggles of Kevin Plawecki and injury to Travis d’Arnaud, the Mets could eventually be forced into looking for catching help on the summer trade market. Ricco spoke to Carig and defended both backstops, asserting that both have proven to be above-average offensive players in the past. Plawecki, however, has batted just .210/.282/.288 in 356 big league plate appearances — a far cry from his .262/.318/.392 batting line in 260 Triple-A plate appearances. And d’Arnaud, of course, has consistently struggled to stay off the disabled list throughout his big league tenure. Carig speculates that Jonathan Lucroy would be a strong fit for the Mets, and it’s hard to argue with the logic. Lucroy could even help out at first base in the absence of Lucas Duda, as he has appeared in 43 games there across the past four seasons.

Phillies right-hander Mark Appel has been placed on the minor league disabled list with a strained right shoulder, tweets Matt Breen of the Philadelphia Inquirer. Appel, the former No. 1 overall pick acquired by the Phillies in this offseason’s Ken Giles blockbuster, has been experiencing diminished velocity of late, Breen notes. The extent of the injury is unclear, but it appears possible that the shoulder has been bother Appel for a few starts; he’s allowed 15 earned runs in his past 16 1/3 innings after getting off to a nice start with the Phillies’ Triple-A affiliate.

ESPN’s Keith Law has published an updated list of the game’s Top 25 prospects (Insider subscription required and recommended), and it’s headlined by a pair of NL East prospects: Nationals right-hander Lucas Giolito (No. 1) and Phillies shortstop J.P. Crawford (No. 2). Law provides some insight into each of the 25 names on his ranking and also lists five honorable mentions that narrowly missed the cut.

Mets manager Terry Collins put a swift end to speculation on Matt Harvey’s immediate future, at least for the time being. The righty will make his next scheduled start, as Mike Puma of the New York Post was among those to report. “We saw some real positive things early in the game [Tuesday] night,” Collins told the media. “When he hit a wall in the fifth inning, I said I wasn’t surprised. I told Matt about it, I said I was proud of the fact the way he prepared for it and we saw some positive things early in the game.” Collins maintains that the Mets are focused on the big picture with Harvey, saying that the right-hander is “too big a piece to write him off” or to be put in the bullpen. MLBTR readers weighed in this morning on what the Mets should do, with a slight plurality preferring to see the club skip a Harvey start rather than maintaining the status quo or taking more drastic action.

A few more notes on the NL East…

Yoenis Cespedes has been as good as anyone could have hoped since returning to the Mets, and Ken Davidoff of the New York Post wonders whether there’s any chance of the sides getting back together on a new deal. Cespedes seems well on his way to returning to the open market via his opt-out clause, of course, having gotten off to a tremendous start to the season in advance of a considerably weaker free agent class than the one in which he found himself last winter. The 30-year-old is batting .309/.387/.678 and leading the National League in OPS, slugging percentage and RBIs while holding the MLB lead with 15 home runs. Assistant GM John Ricco said that there’s been no talk between the two sides about working out a new deal, though he also acknowledged: “There’ll be a time and place for that and I think when that time comes, we’ll see what happens.” Davidoff suggests multiple hypothetical offers the Mets could make to Cespedes now, though the slugging outfielder could ultimately find himself positioned as the top free agent on the market, especially now that division-rival Stephen Strasburg is off the market following a seven-year extension.

Left-hander Joe Beimel had a visit with Dr. James Andrews after his recent minor league agreement with the Marlins fell through due to physical concerns, reports ESPN’s Jerry Crasnick (links to Twitter). Andrews gave Beimel’s shoulder and elbow a clean bill of health, though clearly there was something that gave Miami some degree of pause. Of course, for a 39-year-old veteran of 13 big league seasons, it wouldn’t be surprising to see some degree of wear and tear in his arm. Beimel has pitched well with the Mariners across the past two seasons, working to a combined 3.12 ERA in 92 1/3 innings and holding lefties to a .226/.281/.381 batting line and whiffing nearly 18 percent of the same-handed opponents he faced in that time.

Nationals right-hander Shawn Kelley has quietly been one of the game’s most dominant relievers in recent years, writes MLB.com’s Mike Petriello. As Petriello notes, the Nationals’ new setup man, who signed a three-year contract in free agency this winter, has the lowest ERA in baseball across the past calendar year, and while some may think his dominance has come out of nowhere, he’s actually been strong dating back to 2013, Petriello points out. Only 11 pitchers registered a higher strikeout percentage in that time. Kelley is enjoying his best season yet, and while he hasn’t altered his pitch selection much, Petriello explains that Kelley has significantly improved the command of his fastball, moving the pitch more to the edge of the zone as opposed to the center of the plate, resulting in more strikeouts and more pop-ups. The bottom-line result for Kelley has been a 1.13 ERA with a 22-to-3 K/BB ratio in 16 innings this season

The Mets polished off a three-game sweep of the Brewers today and now head into a big three-game series with the NL East-leading Nationals. New York goes into the series 1.5 games behind Washington. Here’s the latest from the Amazins…

Lucas Duda underwent tests on his bad back this morning and he’ll be re-evaluated by team doctors on Monday, manager Terry Collins told reporters (including Peter Botte of the New York Daily News). Collins admitted that he’s “really concerned” about his first baseman’s status, with David Wright also seemingly implying that Duda could miss some time. Duda is off to a slow start, hitting .231/.297/.431 with seven homers through his first 145 PA.

Asdrubal Cabrera wasn’t considered a marquee signing during the Mets’ offseason but the veteran infielder has thus far delivered a very solid performance, the New York Post’s Zach Braziller writes. Cabrera is hitting .278/.333/.373 through 171 plate appearances and despite some subpar defensive metrics, he’s been a valuable fill-in at shortstop with Wilmer Flores injured.

Does Stephen Strasburg’s extension with the Nationals offer any lessons for the Mets and Matt Harvey? Newsday’s David Lennon notes that at the moment, the Mets are simply trying to get Harvey on track after a very rough start to his season. The two aces invite comparison in many ways (i.e. both Scott Boras clients, both early-career Tommy John patients), though perhaps the most interesting point of divergence is how the Nats famously shut down Strasburg in the season following his TJ surgery rather than use him down the stretch and into the postseason, whereas the Mets used Harvey throughout their run to the World Series last year.

The Blue Jays have told teams that right-handed reliever Drew Storen is available, reports Bob Elliott of the Toronto Sun. Storen, whom the Jays acquired from the Nationals for outfielder Ben Revere in the offseason, is on an $8.38MM salary this year and is then slated to become a free agent. Formerly a capable late-game option with the Nats, Storen has already allowed 13 runs on 22 hits in his first 15 innings with the Jays. To his credit, the 28-year-old has continued his career-long trend of posting quality strikeout and walk rates (9.6 and 2.4 this season, respectively), but PITCHf/x indicates that his velocity is down a couple miles per hour.

Now let’s check in on some other clubs from baseball’s two East divisions:

If lefty starter Eduardo Rodriguez and right-handed reliever Carson Smith don’t serve as adequate in-season reinforcements, the 26-17 Red Sox are open to acquiring outside talent and increasing their $201MM-plus payroll in the process, writes Evan Drellich of the Boston Herald. Team ownership is “as committed as ever” to putting a winner on the field after enduring back-to-back last-place finishes, said club president Sam Kennedy.

The Phillies’ front office has put Pete Mackanin in a tough position with first baseman Ryan Howard, whom the manager is hesitant to bench, opines Ryan Lawrence of Philly Voice. Howard is hitting a paltry .161/.233/.381 in 133 plate appearances, but he’s a popular figure in the clubhouse and Mackanin doesn’t want to send the wrong message by removing him from the lineup in favor of recent call-up and platoon mate Tommy Joseph. Thus, writes Lawrence, the front office should step in and handle it for Mackanin. Howard, 36, has long been in decline and is likely in his last year with the Phillies, who will buy him out for $10MM at season’s end in lieu of paying him $23MM to remain on the team in 2017. Considering both that and Howard’s weak output, it would make sense for the Phillies to give Joseph the lion’s share of time at first.

A scout who has followed Matt Harvey since his amateur days offered his assessment of the struggling Mets right-hander to Kevin Kernan of the New York Post. “There’s no deception in his delivery. “He is throwing across his body and the hitters are getting a good look at everything,” said the scout, who added that Harvey looks out of shape and is presenting “no fear factor, no intimidation.”
